Invention field
The present invention relates to produce the method and apparatus of particle (chaff), it is for the production of the particle that uses in Wood composite material is produced, and for the production of the method for Wood composite material.
Background of invention
Various pressing methods are that prior art is known, and wherein, plastic raw material is melted, with optional additive with colouring agent mixes and mould by certain profile pushes to form product.When from mould out the time, product namely becomes or near its net shape.From mould out, product can be imported into calibrating installation, and product is provided as accurately and final size therein, and further imports the water receiver as cooler performance function.Product is sawn into desirable size in production line.The most often with particle or powder type raw material is dosed to extruder.
Different types of wood plastic composite (wood-plastic composite materials) and production method thereof also are that prior art is known.To make by wooden based component (based on the composition of timber, wood-based constituents) and different types of processing aid are added in the matrix plastic as filler by the wood plastic composite of pressing method production.Employed wooden based component is wood chip normally, but also can be wood chip or chemical paper fiber.Raw material is dosed to extruding with graininess usually.Therefore, at first must be squeezed into particle to wooden based raw material and plastics with separately method.Additional treatments can increase production cost.Yet possible is that raw material components itself is fed into extruder and is made into product.This requires to use different types of positive feed equipment, even so that raw material is inhomogeneous and proportion is low, also can guarantee stable charging.The method is called as direct charging.
When the wooden based component that adds matrix to when expectation can be reinforced profile, must consider fibre length and the shape of institute's adding ingredient.The wood chip that is used for wood plastic composite is so made size and shape so that in fact it is not reinforcing product, but on the contrary, only plays the function of filler in plastic substrate.
Before actual treatment, usually need dried wood chips or wood chip, because the high water capacity in the filler can reduce the quality of manufacturing product.In the reason process, vaporized water vapour produces bubble to profile herein, and it affects outward appearance and the mechanical performance of product.The drying of carrying out as additional treatments is unnecessary step, and reason is fringe cost and risk of explosion.
Making Wood composite material with the wood waste that is processed into particle form and regenerated plastics also is that prior art is known.Paper using and thermoplastic are made Wood composite material and also can be learnt from publication US 4874095, and use based on timber with based on the material manufacturing Wood composite material of plastics and also can learn from publication US 20020034629 and US 3718536.
Goal of the invention
The present invention seeks to eliminate the above-mentioned deficiency of mentioning.Specific purposes of the present invention are open novel method and equipment for the production of the waste material particle---described waste material particle is produced in the Wood composite material and is needed, and the novel method and the equipment that are further used for producing Wood composite material.Another object of the present invention is open new method and device for the treatment of adhesive laminate waste.
Summary of the invention
